gnome-settings-daemon listens for drm udev events to trigger automatic layout updates. As it turns out, upower's current definition for "is this machine docked" is "does this machine have more than one output connected", and it...also listens for udev events - specifically from drm, not dock devices - to trigger updating its internal value.
(upower doesn't use any of the actual ACPI dock detection mechanisms because most modern docks don't actually register as ACPI docking stations, so they don't show up at all in ACPI) So in this particular case, upower doesn't know anything that g-s-d doesn't. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732867 Title: gnome-display-properties monitor layout not saved when re-docking (and display port) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/732867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
